Build Your Library vs BookShark

Checked October 29, 2026No affiliate links. Programs never pay to appear.

The main differences

Both plan a year around real books over 36 weeks. Build Your Library sells the plan alone, as a PDF of lesson plans for $39.95 a level, with Charlotte Mason narration and copywork, and you buy or borrow the books and add your own math. BookShark ships the guides and the books together in an all-subject package that includes math and handwriting, at $1,040.94 for Level C on sale. The choice is mostly how much of the gathering you want to do yourself.

Build Your Library

Build Your Library is a literature-based curriculum with Charlotte Mason methods, sold as one PDF of lesson plans per level from kindergarten to 12th grade. Each level follows a history theme, and the plans give a daily and weekly schedule for 36 weeks with a reading list, narration cards, copywork, vocabulary, poetry memorization, timeline figures, mapwork, science lessons and art projects. You buy or borrow the books yourself, add your own math, and may want separate spelling and grammar programs.

Does well: A full year of lesson plans costs $39.95, so most of the spending goes to books, which you can also borrow from a library.

Watch for: Math is not included, and you may need separate spelling and grammar programs.

BookShark

BookShark is a literature-based curriculum organized by levels rather than grades: history, science and language arts are taught through read-alouds, readers and other real books, on a 36-week, 4-day schedule set out in instructor's guides. An all-subject package for one child includes the guides, the books, language arts, handwriting, science and a math program, plus optional online access for reading schedules and auto-graded assessments. Levels run from pre-K (ages 4 to 5) to high school.

Does well: Instructor's guides plan 36 weeks on a 4-day schedule, leaving a fifth day free, with answer keys, discussion questions and background notes.

Watch for: A Level C all-subject package costs over $900 even at 20% off.

How we label

Every fact on a card was read on the publisher's own website on the date shown, and the page it came from is linked. A fact we could not confirm there is left out. Costs are for one child and one year of the main package, as the publisher's page showed them that day; prices and sales change. Method and format are the publisher's own description where it gives one. The only thing we say about religion is one label, secular or faith-based, given by the rule above; where the publisher's pages don't settle it, the card has no label.
